Questão jurídica principal
Whether the appeal to the Federal Supreme Court against the cantonal security-for-costs order was admissible as an interim decision under Art. 93 BGG.
Decisão extraída
The appellant failed to show any exceptional ground for immediate review; neither a non-reparable legal disadvantage nor the conditions for immediate final judgment were apparent.
Fundamentação extraída
An order requiring security for costs is an interim decision. Such decisions are only appealable exceptionally under Art. 93 BGG, and the burden to establish admissibility lies with the appellant. The appeal contained no argument on admissibility, and no qualifying irreparable legal harm was evident.
